The magnetic properties of Nd 6 Fe 1 3 Au were studied by means of magnetic measurements and iron-57 Mossbauer spectroscopy. It is shown that magnetic ordering of the Fe moments occurs at temperatures much above room temperature (T N = 408 K). At low temperatures, the net moment of Nd 6 Fe 1 3 Au is very small owing to mutual compensation of the contributions of the various magnetic sublattices involved. High-field measurements made at 4.2 K show that ferromagnetic alignment of the sublattice moments is reached in two steps via first-order magnetic phase transitions. The Mossbauer spectra reveal that the Zeeman splitting gradually decreases with increasing temperature and that the average hyperfine field is zero at 435 K and above. Between 325 K and 411 K the area in the Mossbauer spectra due to the ordered magnetic component decreases gradually as it is replaced by a quadrupole doublet.
